Nutritionist warns that drinking water like Brady could kill ordinary people

Copying Tom Brady's hydration routine could be very dangerous for the average person.

In his book, "The TB12 Method," the New England Patriots quarterback recommends people drink at least half their body weight in ounces of water each day.

"That's the minimum," the book instructs. "Ideally, you'll drink more than that, and with added electrolytes, too. This makes sense, considering the composition of our bodies."

Brady himself reportedly drinks more than 37 glasses of water a day, but nutritionist Ariane Resnick warns that consuming that much H2O puts people at risk of hyponatremia - a condition that occurs when the sodium level in blood is too low, increasing the risk of a stroke.

"Increase your water intake by two to four glasses a day and you will be better hydrated, your skin may look less wrinkled, and you'll likely feel better," Resnick told Holly Van Hare of the Daily Meal. "But I'd avoid trying to become a human aquarium."
